Question

Write the expression for energy density of electric field in free space​

Answer 1

Answer:

We can also view the energy as being stored in the electric field produced by the separated.

the energy density, i.e. the energy per unit volume, in the electric field.

Answer 2

The energy density is total amount of energy per unit volume.

Explanation:

Energy density :

Total amount of energy per unit volume it is called energy density.

The energy stored between the plates of capacitor is equal to the stored amount of energy per unit volume in electric field multiple by volume between of plates .

The unit of energy density of electric field is J/m³.

In mathematically term,

$U_{E}=\dfrac{1}{2\epsilon_{0}}E^2$

Where, E = energy per unit volume in electric field.

Hence, The energy density is total amount of energy per unit volume.
